Description

Technical Field

[0001] The present invention relates to the technical field of edge grinding devices for stone processing, in particular to an edge grinding device for stone processing and a working method thereof. Background Art

[0002] The stone processing edging device is a mechanical device specially used for chamfering the edges of stone. It is usually used in the processing of stone slabs, countertops and decorative components. Its core function is to physically cut the edge of the stone through a rotating grinding wheel to eliminate burrs, adjust the shape and improve the surface finish to meet decoration, installation or safety requirements.

[0003] At present, when the existing stone processing and edging device is in use, the grinding wheel structure in the edging device will rub against the stone for a long time during operation. Therefore, it is necessary to use tools to regularly check the degree of wear of the grinding wheel. When the wear is serious, the grinding wheel structure needs to be replaced. However, since there are a large number of grinding wheel structures and the grinding wheel structures are usually located inside the edging device, the inspection and replacement time is long when the grinding wheel structures are inspected and replaced, resulting in a problem of long equipment downtime.

[0004] In view of the above problems, it can be found that it is difficult to avoid the above problems at the same time when using the existing stone processing edge grinding devices on the market, and even if they can be solved, they need to be solved with the help of external tools, which makes it impossible to achieve the desired effect. Therefore, we propose a stone processing edge grinding device and a working method. Summary of the Invention

[0011] Preferably, the output end of each second stepper motor is fixedly connected to the second rotating shaft, a first grinding wheel is provided on the outer side of each second rotating shaft, the inner wall of each first grinding wheel and the inner wall of the second rotating shaft are commonly threadedly connected with a bolt, and two circular openings are opened on the upper surface of each first grinding wheel.

[0012] Preferably, the replacement unit includes two first movable plates and a support block, and the two first movable plates are jointly fixedly connected to the second movable plate on one side near each other, and the inner wall of the second movable plate is fixedly connected to two second hydraulic rods, and the telescopic ends of the two second hydraulic rods are jointly fixedly connected to the lifting and lowering plate, and the interior of the second movable plate is slidably connected to two groups of sliding plates, and the number of each group of sliding plates is two, and the outer surface of each sliding plate contacts the inner wall of the second movable plate, and the bottom surface of each sliding plate is fixedly connected to two circular clamping shafts and diamond blocks, and the upper surface of the support block is fixedly connected to four groups of support plates, the number of each group of support plates is two, and the outer surface of each support plate is fixedly connected to a limiting cylinder.

[0013] Preferably, two third stepper motors are arranged above the support block, and the output end of each of the third stepper motors is fixedly connected to a second threaded shaft, the outer surfaces of the two second threaded shafts are jointly rotatably connected to the inner walls of two of the support legs, and the inner wall of each of the first movable plates is threadedly connected to the outer surface of the second threaded shaft.

[0014] Preferably, the automatic pushing unit includes a storage box, the upper surface of the storage box is fixedly connected to the bottom surfaces of two third stepper motors, the front of the storage box is fixedly connected to the back of the support block, the front of the storage box is fixedly connected to two self-locking motors, the output end of each self-locking motor is fixedly connected to an extrusion shaft, the outer surface of each extrusion shaft is rotatably connected to the inner wall of the storage box, the inner bottom wall of the storage box is fixedly connected to two groups of pressure springs, the number of pressure springs in each group is two, the top of each pressure spring is fixedly connected to a rectangular box, the two side surfaces of each rectangular box are in contact with the outer surfaces of the two extrusion shafts, and three second grinding wheels are provided on the outside of each rectangular box.

[0015] A working method of an edge grinding device for stone processing comprises the following steps: S1: When this device needs to be used, the first hydraulic rod is controlled to extend, indirectly pushing the first grinding wheel to move to the left. When the first grinding wheel moves to the left, the circular groove on the outer surface of the first grinding wheel will contact the bull's eye bearing. Therefore, the first grinding wheel will push the bull's eye bearing, the circular shaft and the extension plate to move toward the force spring, thereby observing the position of the extension plate when it moves to the scale plate. When the first grinding wheel moves to the specified position, the first hydraulic rod will stop running. It should be understood here that the specified position of the first grinding wheel refers to the position when the frontmost position in the groove on the surface of the first grinding wheel contacts the bull's eye bearing. Therefore, the shorter the distance the extension plate moves to the scale plate position, the more serious the wear of the first grinding wheel. Subsequently, the staff only needs to observe the position of the scale plate and the extension plate to determine whether the first grinding wheel needs to be replaced; S2: When the first grinding wheel needs to be replaced, the first hydraulic rod is also controlled to extend. When the first grinding wheel moves to the bottom of the second movable plate, the second hydraulic rod can be controlled to operate. The power generated by the operation of the second hydraulic rod drives the sliding plate to move downward. The downward movement of the sliding plate will further push the circular clamping shaft and the diamond block to move downward. At this time, the second stepper motor is controlled to operate counterclockwise. When the second stepper motor is operated, the rotating power generated will drive the second rotating shaft to rotate, so that the second grinding wheel can be disassembled. When the disassembly is completed, the third stepper motor will drive the second threaded shaft to rotate, and finally drive the first movable plate and the second movable plate to move to the left. As the third stepper motor continues to operate, the disassembled first grinding wheel will move between two adjacent limiting cylinders, and the two adjacent limiting cylinders will be in the grooves on the surface of the first grinding wheel. As the second hydraulic rod continues to extend, it will eventually push the circular clamping shaft out of the clamping relationship with the first grinding wheel. Then the third stepper motor continues to operate, driving the second movable plate to move above the second grinding wheel. Then the second hydraulic rod is also controlled to operate, driving the circular clamping shaft to clamp into the inside of the second grinding wheel; S3: When the second grinding wheel at the top is replaced, the self-locking motor will run, driving the extrusion shaft fixed at its output end to rotate. It should be understood here that the directions of rotation of the two extrusion shafts are opposite, so the extrusion shaft will push the four rectangular boxes to move upward, and further drive the two second grinding wheels above the rectangular box to move upward until the second grinding wheel at the top moves to a position flush with the upper surface of the storage box. It should be understood here that the self-locking motor will lock the extrusion shaft when it is not running, so that the extrusion shaft cannot rotate. Therefore, when the circular card shaft moves downward and is connected to the inside of the second grinding wheel, it will not push the second grinding wheel to move downward, and the surface of the extrusion shaft is covered with a layer of rubber. The large friction coefficient can better ensure that the rectangular box will not move downward due to pressure. Therefore, multiple second grinding wheels can be placed inside the rectangular box at the same time.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention is provided with a self-inspection mechanism, which can automatically detect the degree of wear of the grinding wheel in the stone processing equipment and display the degree of wear of the grinding wheel. The staff can know at a glance whether the grinding wheel needs to be replaced, thereby eliminating the need for the staff to use tools to check the degree of wear of the grinding wheel.

[0017] 2. The present invention provides a replacement unit, which can automatically replace multiple grinding wheels that are severely worn in stone processing equipment at one time, thereby effectively avoiding the tedious step of regularly using tools to dismantle and replace multiple grinding wheels when the equipment is in use.

[0018] 3. The present invention is provided with an automatic pushing unit. The automatic pushing unit can be used to place multiple grinding wheels to be replaced inside the storage box, and the grinding wheels to be replaced can be transported to a suitable replacement position for replacement. By providing a self-inspection mechanism, a replacement unit and an automatic pushing unit, the problem of inconvenience in replacing the grinding wheel during use of the equipment can be effectively avoided.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1: Please refer to Figure 1 、 Figure 7 and Figure 8 The present invention provides a technical solution: a stone processing edging device, which is improved accordingly with respect to the technical problems mentioned in the background technology, comprising a fixing frame 1, a self-checking mechanism 2 is provided above the fixing frame 1, and a replacement mechanism 3 is provided on the left side of the fixing frame 1; The self-checking mechanism 2 can check the wear degree of the friction wheel.

[0023] As a further limitation of the self-inspection mechanism 2 of the present invention, the self-inspection mechanism 2 includes two groups of support legs 201, each group of support legs 201 has two numbers, and the sides of the two groups of support legs 201 close to each other are fixedly connected to the two sides of the fixing frame 1 respectively, wherein the outer surfaces of the two support legs 201 are commonly fixedly connected to a fixing plate 202, and the inner wall of the fixing plate 202 is fixedly connected to two groups of force springs 224, and the number of each group of force springs 224 is two, and the ends of each group of force springs 224 away from each other are fixedly connected to a circular shaft 219, and the number of each circular shaft 219 is two, and the end of each circular shaft 219 away from the force spring 224 is fixedly connected to a bull's eye bearing 222, and each circular shaft 21 9 is fixedly connected to the outer surface of the plate 202 with an extension plate 221, and the upper surface of the fixed plate 202 is fixedly connected to two groups of scale plates 220, and the number of each group of scale plates 220 is two. The inner wall of the fixed plate 202 is fixedly connected to two groups of limit shafts 223, and the number of each group of limit shafts 223 is two. The interior of each circular shaft 219 is slidably connected to the outer surface of the limit shaft 223. By setting up a self-inspection mechanism 2, the self-inspection mechanism 2 can automatically detect the degree of wear of the grinding wheel in the stone processing equipment, and the degree of wear of the grinding wheel can be displayed. The staff can know at a glance whether the grinding wheel needs to be replaced, thereby eliminating the need for the staff to use tools to check the degree of wear of the grinding wheel.

[0024] See also Figure 4The inner wall of the fixed frame 1 is rotatably connected to two gears 218, and the outer surfaces of the two gears 218 are engaged with a toothed belt 209. The right side of the other supporting leg 201 is fixedly connected to the first support seat 208, and the upper surface of the first support seat 208 is fixedly connected to the first stepper motor 207. The output end of the first stepper motor 207 is fixedly connected to the first rotating shaft 217, and the outer surface of the first rotating shaft 217 is rotatably connected to the inner wall of the other supporting leg 201. The left end of the first rotating shaft 217 is fixedly connected to the right end of one of the gears 218. By providing the first stepper motor 207, the operation of the first stepper motor 207 can drive the first rotating shaft 217 to rotate, and further drive a gear 218 to rotate, thereby driving the toothed belt 209 to rotate, so that the toothed belt 209 drives the stone to be processed to move.

[0025] See also Figure 2 The two sets of supporting legs 201 are fixedly connected to the side surface of the long plate 204 on which the two sets of supporting legs 201 are close to each other. The inner wall of the long plate 204 is threadedly connected to the first threaded shaft 206. The top of the first threaded shaft 206 is fixedly connected to the rotating plate 205. The outer surface of the first threaded shaft 206 is rotatably connected to the lifting plate 225. The bottom surface of the lifting plate 225 is fixedly connected to a plurality of identical fixed wheels 226. The upper surface of the lifting plate 225 is fixedly connected to two directional shafts 203. The outer surface of each directional shaft 203 is slidably connected to the interior of the long plate 204. By providing a rotating plate 205, the rotation of the rotating plate 205 can drive the first threaded shaft 206 to rotate. The threaded connection relationship between the first threaded shaft 206 and the long plate 204 can drive the lifting plate 225 to move upward, thereby adjusting the height of the fixed wheel 226 to adapt to stone plates of different heights. The existence of the directional shaft 203 can prevent the lifting plate 225 from rotating, so that the lifting plate 225 can only move up and down.

[0026] See also Figure 4 Three first hydraulic rods 216 are fixedly connected to the inner wall of the fixed frame 1, and the telescopic ends of the three first hydraulic rods 216 are commonly fixedly connected to the push plate 212. Two groups of second stepper motors 211 are fixedly connected to the inner wall of the push plate 212. The number of second stepper motors 211 in each group is two. By providing the first hydraulic rod 216, the first hydraulic rod 216 can be used to push the push plate 212 to move, thereby adjusting the position of the second stepper motor 211.

[0027] See also Figure 2 and Figure 3The output end of each second stepper motor 211 is fixedly connected to the second rotating shaft 213, and a first grinding wheel 210 is provided on the outside of each second rotating shaft 213. The inner wall of each first grinding wheel 210 and the inner wall of the second rotating shaft 213 are both threadedly connected with a bolt 214. Two circular openings 215 are provided on the upper surface of each first grinding wheel 210. By providing the bolts 214 and utilizing the threaded connection relationship between the bolts 214 and the first grinding wheel 210 and the second rotating shaft 213, the first grinding wheel 210 can be installed on the second rotating shaft 213.

[0028] The specific implementation of this embodiment is as follows: when the device is needed, the stone to be edged is placed on the surface of the toothed belt 209, and it is necessary to apply rotational power to the rotating plate 205 in advance to drive the first threaded shaft 206 to rotate. The threaded connection between the first threaded shaft 206 and the long plate 204 can drive the first threaded shaft 206 and the lifting plate 225 to move, so that the fixed wheel 226 fixed on the bottom surface of the lifting plate 225 is in contact with the upper surface of the stone plate. Therefore, when the stone plate is placed on the surface of the toothed belt 209, the fixed wheel 226 will limit the stone plate, so that the stone plate It can only move forward and backward along the conveyor belt, and then control the first hydraulic rod 216 to operate, and use the first hydraulic rod 216 to pull the push plate 212 and the second stepper motor 211 fixed to the inner wall of the push plate 212 to move, which can drive the second stepper motor 211 to move closer to the direction of the stone. Therefore, the first grinding wheel 210 set above the second stepper motor 211 will contact one side of the stone. Then control the second stepper motor 211 to operate, and use the power generated by the second stepper motor 211 when it is running to drive the first grinding wheel 210 to rotate, so that the first grinding wheel 210 can be used to grind the stone. When the stone processing is completed, the first hydraulic rod 216 is controlled to push the push plate 212, the second stepper motor 211 and the first grinding wheel 210 to reset to the left. When it is necessary to check the wear degree of the first grinding wheel 210, the first hydraulic rod 216 is also controlled to extend to indirectly push the first grinding wheel 210 to move to the left. When the first grinding wheel 210 moves to the left, the circular groove on the outer surface of the first grinding wheel 210 will contact the bull's eye bearing 222, so the first grinding wheel 210 will push the bull's eye bearing 222, the circular shaft 219 and the extension plate 221 to move toward the force spring 224, thereby The first hydraulic rod 216 stops operating to observe the position of the scale plate 220 to which the extension plate 221 moves. When the first grinding wheel 210 moves to the designated position, it should be understood that the designated position of the first grinding wheel 210 refers to the position where the frontmost position in the groove on the surface of the first grinding wheel 210 contacts the bull's eye bearing 222. Therefore, the shorter the distance the extension plate 221 moves toward the scale plate 220, the more serious the wear of the first grinding wheel 210. Subsequently, the staff only needs to observe the position of the scale plate 220 and the extension plate 221 to determine whether the first grinding wheel 210 needs to be replaced.

[0029] Example 2: Please refer to Figure 1 、 Figure 2 、 Figure 5 and Figure 6 The present invention provides a technical solution: a grinding device for stone processing. The present invention makes corresponding improvements to the technical problems mentioned in the background technology. The replacement mechanism 3 includes a replacement unit 31. The replacement unit 31 is arranged on the left side of the fixed frame 1. The replacement unit 31 can automatically replace the friction wheel that is severely worn.

[0030] As a further limitation of the replacement mechanism 3 of the present invention, the replacement unit 31 includes two first movable plates 3104 and a support block 3107. The two first movable plates 3104 are fixedly connected to a second movable plate 3103 on one side close to each other. The inner wall of the second movable plate 3103 is fixedly connected to two second hydraulic rods 3112. The telescopic ends of the two second hydraulic rods 3112 are fixedly connected to a lifting and pressing plate 3110. The interior of the second movable plate 3103 is slidably connected to two groups of sliding plates 3111. The number of each group of sliding plates 3111 is two, and the outer surface of each sliding plate 3111 is in contact with the second movable plate 3103. 103, the bottom surface of each sliding plate 3111 is fixedly connected to two circular clamping shafts 3108 and diamond blocks 3109, the upper surface of the support block 3107 is fixedly connected to four groups of support plates 3105, and the number of each group of support plates 3105 is two. The outer surface of each support plate 3105 is fixedly connected to the limiting cylinder 3106. By setting up a replacement unit 31, the replacement unit 31 can be used to automatically replace multiple grinding wheels that are severely worn in the stone processing equipment at one time, thereby effectively avoiding the tedious steps of regularly using tools to dismantle and replace multiple grinding wheels when the equipment is in use.

[0031] See also Figure 1 、 Figure 2 and Figure 5 Two third stepper motors 3101 are arranged above the support block 3107, and the output end of each third stepper motor 3101 is fixedly connected to the second threaded shaft 3102. The outer surfaces of the two second threaded shafts 3102 are jointly rotated and connected to the inner walls of two of the support legs 201. The inner wall of each first movable plate 3104 is threadedly connected to the outer surface of the second threaded shaft 3102. By setting up the third stepper motor 3101 to operate, the second threaded shaft 3102 can be driven to rotate, and then the overall position of the first movable plate 3104 can be adjusted.

[0032] The specific implementation of this embodiment is as follows: when the first grinding wheel 210 needs to be replaced, the first hydraulic rod 216 is controlled to push the push plate 212, the second stepping motor 211, the second rotating shaft 213 and the first grinding wheel 210 to move to the left. When the first grinding wheel 210 moves to the bottom of the second movable plate 3103, the second hydraulic rod 3112 can be controlled to operate, and the power generated by the operation of the second hydraulic rod 3112 is used to drive the sliding plate 3111 to move downward. The downward movement of the sliding plate 3111 will further push the circular clamping shaft 3108 and the diamond block 3109 to move downward until the diamond block 3109 and the circular clamping shaft 3108 move to the inner thread connection of the first grinding wheel 210 and the circular groove opened on the upper surface of the first grinding wheel 210. When the circular clamping shaft 3108 and the diamond block 3109 are clamped to the bolt 214 threadedly connected to the inside of the first grinding wheel 210 and the circular opening 215 opened on the upper surface of the first grinding wheel 210, the two second hydraulic rods 3112 are controlled to reset, and the second hydraulic rods 3112 will push the lifting plate 225 to move upward, so that the bottom surface of the lifting plate 225 does not contact the surface of the sliding plate 3111, but the upper surface of the lifting plate 225 contacts the surface of the sliding plate 3111. At this time, the second stepper motor 211 is controlled to run counterclockwise. When the second stepper motor 211 runs, it will generate a rotating force to drive the second rotating shaft 213 to rotate. However, at this time, the first grinding wheel 210 and the bolt 214 above the second stepper motor 211 are respectively The clamping shaft 3108 and the diamond block 3109 are limited, so the second grinding wheel 3206 and the bolt 214 above the second stepping motor 211 cannot rotate. When the second stepping motor 211 is running, the rotational power generated will drive the bolt 214 to move upward, and further drive the bolt 214, the second grinding wheel 3206 and the sliding plate 3111 to move upward synchronously. At this time, the upper surface of the lifting plate 225 will not contact the surface of the sliding plate 3111, so the second grinding wheel 3206 can be disassembled. When the disassembly is completed, the operation of the third stepping motor 3101 will drive the second threaded shaft 3102 to rotate. Therefore, when the second threaded shaft 3102 rotates, it can synchronously drive the first movable plate 3104 by utilizing the threaded connection relationship with the first movable plate 3104. When the movable plate 3104 and the second movable plate 3103 move to the left, the sliding plate 3111, the circular clamping shaft 3108, the diamond block 3109 and the disassembled first grinding wheel 210 inside the second movable plate 3103 will all move to the left. When the bottom surface of the first grinding wheel 210 is no longer in contact with the top of the second rotating shaft 213, the first grinding wheel 210 will move downward again under the action of gravity until the upper surface of the lifting plate 225 contacts the surface of the sliding plate 3111 again. It should be understood here that the surface of each circular clamping shaft 3108 is covered with a layer of rubber, and the circular clamping shaft 3108 is clamped into the inside of the first grinding wheel 210. Therefore, under the action of friction, the first grinding wheel 210 can be driven to move to the left following the clamping shaft.As the third stepper motor 3101 continues to operate, the disassembled first grinding wheel 210 will move between two adjacent limiting cylinders 3106, and the two adjacent limiting cylinders 3106 will be in the grooves on the surface of the first grinding wheel 210. At this time, the third stepper motor 3101 stops running, and the second hydraulic rod 3112 will push the lifting plate 225 to move upward, and further push the sliding plate 3111 to move upward. However, since the limiting cylinder 3106 is in the groove on the surface of the first grinding wheel 210, the first grinding wheel 210 is unable to move upward, but as the second hydraulic rod 3112 continues to extend, it will eventually push the circular clamping shaft 3108 to release the clamping relationship with the first grinding wheel 210. At this time, the first grinding wheel 210 will remain on the surface of the support block 3107. Then the disassembled first grinding wheel 210 is manually removed, and then the third stepper motor 3101 continues to operate, driving the second movable plate 3103 to move to the top of the second grinding wheel 3206. Then, the second hydraulic rod 3112 is also controlled to operate, driving the circular clamping shaft 3108 to release the clamping relationship with the first grinding wheel 210. At this time, the first grinding wheel 210 will remain on the surface of the support block 3107. The shaft 3108 is clamped in the interior of the second grinding wheel 3206. It should be understood that the second grinding wheel 3206 is the same as the first grinding wheel 210. The inner wall is threaded with bolts 214 and the upper surface also has two circular openings 215. Then the third stepper motor 3101 starts to run in the reverse direction, and the second grinding wheel 3206 moves to the right until it moves above the second stepper motor 211. Then the first hydraulic rod 216 drives the push plate 212 to move downward, which further drives the second grinding wheel 3206 to move downward. The second grinding wheel 3206 is rotated until it wraps around the second rotating shaft 213. The second stepper motor 211 is then controlled to rotate slowly clockwise, which drives the second rotating shaft 213 to rotate. Note that at this time, the second grinding wheel 3206 and the circular clamping shaft 3108 are constantly under pressure from the second hydraulic rod 3112 and do not rotate under the action of the circular clamping shaft 3108. Therefore, the bolt 214 threadedly connected to the inner wall of the second grinding wheel 3206 will gradually thread into the inner wall of the second rotating shaft 213, thus completing the replacement purpose.

[0033] Example 3: Please refer to Figure 1 and Figure 5 The present invention provides a technical solution: a edging device for stone processing. The present invention makes corresponding improvements to the technical problems mentioned in the background technology. The replacement mechanism 3 also includes an automatic pushing unit 32. The automatic pushing unit 32 is arranged on the left side of the fixed frame 1. The automatic pushing unit 32 can store multiple friction wheels to be replaced and push the friction wheels to be replaced to the replacement position.

[0034] As a further limitation of the replacement mechanism 3 of the present invention, the automatic pushing unit 32 includes a storage box 3201, the upper surface of the storage box 3201 is fixedly connected to the bottom surfaces of the two third stepper motors 3101, the front of the storage box 3201 is fixedly connected to the back of the support block 3107, the front of the storage box 3201 is fixedly connected to two self-locking motors 3203, the output end of each self-locking motor 3203 is fixedly connected to an extrusion shaft 3204, the outer surface of each extrusion shaft 3204 is rotatably connected to the inner wall of the storage box 3201, and the inner bottom wall of the storage box 3201 is fixedly connected to two groups of pressure springs 3202, and the number of each group of pressure springs 3202 is equal. There are two of them, and the top of each pressure spring 3202 is fixedly connected to a rectangular box 3205. The two side surfaces of each rectangular box 3205 are in contact with the outer surfaces of the two extrusion shafts 3204. Three second grinding wheels 3206 are arranged on the outside of each rectangular box 3205. By setting an automatic pushing unit 32, multiple grinding wheels to be replaced can be placed inside the storage box 3201 using the automatic pushing unit 32, and the grinding wheels to be replaced can be transported to a suitable replacement position for replacement. By setting a self-inspection mechanism 2, a replacement unit 31 and an automatic pushing unit 32, the problem of inconvenience in replacing the grinding wheel during use of the equipment can be effectively avoided.

[0035] The specific implementation of this embodiment is as follows: when the second grinding wheel 3206 at the top is replaced, the self-locking motor 3203 will run, driving the extrusion shaft 3204 fixed at its output end to rotate. It should be understood that the two extrusion shafts 3204 rotate in opposite directions, so the extrusion shaft 3204 will push the four rectangular boxes 3205 to move upward, and further drive the two second grinding wheels 3206 above the rectangular boxes 3205 to move upward until the second grinding wheel 3206 at the top moves to a position flush with the upper surface of the storage box 3201. It should be understood that In white, the self-locking motor 3203 will lock the extrusion shaft 3204 when not in operation, so that the extrusion shaft 3204 cannot rotate. Therefore, when the circular clamping shaft 3108 moves downward and is clamped to the inside of the second grinding wheel 3206, it will not push the second grinding wheel 3206 to move downward. The surface of the extrusion shaft 3204 is covered with a layer of rubber. The large friction coefficient can better ensure that the rectangular box 3205 will not move downward due to pressure. Therefore, multiple second grinding wheels 3206 can be placed inside the rectangular box 3205 at the same time, increasing the convenience for workers to use.

[0036] A working method of an edge grinding device for stone processing comprises the following steps: S1: When the device needs to be used, the first hydraulic rod 216 is controlled to extend, indirectly pushing the first grinding wheel 210 to move to the left. When the first grinding wheel 210 moves to the left, the circular groove on the outer surface of the first grinding wheel 210 will contact the bull's eye bearing 222. Therefore, the first grinding wheel 210 will push the bull's eye bearing 222, the circular shaft 219 and the extension plate 221 to move toward the force spring 224. From this, it can be observed to which position the extension plate 221 moves on the scale plate 220. When the first grinding wheel 210 moves to the specified position, the first hydraulic rod 216 will stop operating. It should be understood here that the specified position of the first grinding wheel 210 refers to the position when the frontmost position of the groove on the surface of the first grinding wheel 210 contacts the bull's eye bearing 222. Therefore, the shorter the distance the extension plate 221 moves toward the scale plate 220, the more serious the wear of the first grinding wheel 210. Subsequently, the staff only needs to observe the position of the scale plate 220 and the extension plate 221 to determine whether the first grinding wheel 210 needs to be replaced. S2: When the first grinding wheel 210 needs to be replaced, the first hydraulic rod 216 is also controlled to extend. When the first grinding wheel 210 moves to the bottom of the second movable plate 3103, the second hydraulic rod 3112 can be controlled to operate. The power generated by the second hydraulic rod 3112 when it is running drives the sliding plate 3111 to move downward. The downward movement of the sliding plate 3111 will further push the circular clamping shaft 3108 and the diamond block 3109 to move downward. At this time, the second stepper motor 211 is controlled to operate counterclockwise. When the second stepper motor 211 is running, the rotational power generated will drive the second rotating shaft 213 to rotate, so that the second grinding wheel 3206 can be disassembled. When the disassembly is completed, the third stepper motor 3101 is operated to drive the second threaded shaft 31 02 rotates, eventually driving the first movable plate 3104 and the second movable plate 3103 to move to the left. As the third stepper motor 3101 continues to operate, the disassembled first grinding wheel 210 will move between the two adjacent limiting cylinders 3106, and the two adjacent limiting cylinders 3106 will be in the grooves on the surface of the first grinding wheel 210. As the second hydraulic rod 3112 continues to extend, it will eventually push the circular clamping shaft 3108 out of the clamping relationship with the first grinding wheel 210. Then the third stepper motor 3101 continues to operate, driving the second movable plate 3103 to move above the second grinding wheel 3206. Then, the second hydraulic rod 3112 is controlled to operate in the same way, driving the circular clamping shaft 3108 to clamp into the inside of the second grinding wheel 3206. S3: When the second grinding wheel 3206 at the top is replaced, the self-locking motor 3203 will run, driving the extrusion shaft 3204 fixed at its output end to rotate. It should be understood that the two extrusion shafts 3204 rotate in opposite directions, so the extrusion shaft 3204 will push the four rectangular boxes 3205 to move upward, and further drive the two second grinding wheels 3206 above the rectangular boxes 3205 to move upward until the second grinding wheel 3206 at the top moves to a position flush with the upper surface of the storage box 3201. It should be understood that the self-locking motor When the machine 3203 is not running, the extrusion shaft 3204 will be locked, so that the extrusion shaft 3204 cannot rotate. Therefore, when the circular clamping shaft 3108 moves downward and is clamped to the inside of the second grinding wheel 3206, it will not push the second grinding wheel 3206 to move downward. The surface of the extrusion shaft 3204 is covered with a layer of rubber. The large friction coefficient can better ensure that the rectangular box 3205 will not move downward due to pressure. Therefore, multiple second grinding wheels 3206 can be placed inside the rectangular box 3205 at the same time, increasing the convenience for workers to use.

10. A method for operating a stone processing edge grinding device according to any one of claims 1 to 9, characterized in that: The specific steps include: S1: When the device is needed, the first hydraulic rod (216) is controlled to extend, indirectly pushing the first grinding wheel (210) to move to the left. When the first grinding wheel (210) moves to the left, the circular groove on the outer surface of the first grinding wheel (210) contacts the bull's eye bearing (222). Therefore, the first grinding wheel (210) pushes the bull's eye bearing (222), the circular shaft (219) and the extension plate (221) to move toward the force spring (224). From this, it can be observed to which position the extension plate (221) moves to the scale plate (220). When the first grinding wheel (210) moves to the left, the circular groove on the outer surface of the first grinding wheel (210) contacts the bull's eye bearing (222). When (210) moves to the designated position, the first hydraulic rod (216) stops running. It should be understood that the designated position of the first grinding wheel (210) refers to the position when the frontmost position in the groove on the surface of the first grinding wheel (210) contacts the bull's eye bearing (222). Therefore, the shorter the distance that the extension plate (221) moves toward the position of the scale plate (220), the more serious the wear of the first grinding wheel (210). Subsequently, the staff only needs to observe the position of the scale plate (220) and the extension plate (221) to determine whether the first grinding wheel (210) needs to be replaced. S2: When the first grinding wheel (210) needs to be replaced, the first hydraulic rod (216) is also controlled to extend. When the first grinding wheel (210) moves to the bottom of the second movable plate (3103), the second hydraulic rod (3112) can be controlled to operate. The power generated by the operation of the second hydraulic rod (3112) drives the sliding plate (3111) to move downward. The downward movement of the sliding plate (3111) further pushes the circular clamping shaft (3108) and the diamond block (3109) to move downward. At this time, the second stepper motor (211) is controlled to operate counterclockwise. The rotational power generated by the operation of the second stepper motor (211) drives the second rotating shaft (213) to rotate, thereby completing the disassembly of the second grinding wheel (3206). After the disassembly is completed, the operation of the third stepper motor (3101) drives the second threaded shaft (310 2) rotate, and finally drive the first movable plate (3104) and the second movable plate (3103) to move to the left side. As the third stepper motor (3101) continues to operate, the disassembled first grinding wheel (210) will move between two adjacent limiting cylinders (3106), and the two adjacent limiting cylinders (3106) will be in the grooves on the surface of the first grinding wheel (210). As the second hydraulic rod (3112) continues to extend, it will eventually push the circular clamping shaft (3108) out of the clamping relationship with the first grinding wheel (210). Then the third stepper motor (3101) continues to operate, driving the second movable plate (3103) to move to the top of the second grinding wheel (3206). Then, the second hydraulic rod (3112) is also controlled to operate, driving the circular clamping shaft (3108) to clamp inside the second grinding wheel (3206); S3: When the second grinding wheel (3206) at the top is replaced, the self-locking motor (3203) will run, driving the extrusion shaft (3204) fixed at its output end to rotate. It should be understood that the two extrusion shafts (3204) rotate in opposite directions, so the extrusion shaft (3204) will push the four rectangular boxes (3205) to move upward, and further drive the two second grinding wheels (3206) above the rectangular boxes (3205) to move upward until the second grinding wheel (3206) at the top moves to a position flush with the upper surface of the storage box (3201). It is understood that the self-locking motor (3203) will lock the extrusion shaft (3204) when not in operation, so that the extrusion shaft (3204) cannot rotate. Therefore, when the circular clamping shaft (3108) moves downward and is clamped to the inside of the second grinding wheel (3206), it will not push the second grinding wheel (3206) to move downward. The surface of the extrusion shaft (3204) is covered with a layer of rubber. The large friction coefficient can better ensure that the rectangular box (3205) will not move downward due to pressure. Therefore, multiple second grinding wheels (3206) can be placed inside the rectangular box (3205) at the same time.
